start-pulseaudio-x11 xprop memory leak?

I'm running LMDE 2 (Betsy) on a system with ample memory, so it gives offending processes a lot of leeway to abuse memory without being noticed. I just looked at top and found this:
  PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
 3713 <user> 20 0 4336 108 0 S 0.0 0.0 0:00.00 `- /bin/sh /usr/bin/start-pulseaudio-x11
 3714 <user> 20 0 1240092 1.153g 2268 S 0.0 3.7 0:15.90 `- /usr/bin/xprop -root -spy

That seems like an insane amount of memory for xprop to legitimately allocate, so I'm assuming there's a leak of some kind.
